The RX Supercar

2016BelJump
Rallycross races are held on approximately 1 km race circuits. The tracks are technically very challenging with spectacular corners and consist of constantly changing surfaces due to the mixture of asphalt and gravel. Even with the demanding nature of the courses, the average track speed is approximately 100 km/h!The races are based on four qualifying heats, two semi-finals and a final with five to six cars competing head-to-head.

The Supercar category is based on the standard production car, which retains the original silhouette but with minor alterations to the external panels. The minimum weight of a 2000 cc RX Supercar is 1320 kg (including the driver).

Compared to WRC, the Rallycross regulations offer more freedom to allow teams to build an even more specialised race car using an even wider range of engineering solutions.

Supercars can use either a 1600 cc or 2000 cc turbocharged engine. Any engine produced by the original vehicle manufacturer can be used as a base. Our current engine supplied by Pipo Moteur of France (Peugeot 206 WRC, Ford Focus/Fiesta WRC factory engine supplier) is a 2-liter turbo engine using a 45 mm turbo restrictor.

Compared to a figure of 300 BHP/550 Nm for a current WRC car, our RX car produces approximately 600 BHP and 900 Nm of torque.

This results in the car accelerating to 100 km/h in approximately 2 seconds.

Transmission of a rallycross supercar is a four-wheel-drive system linked to a manual sequential gearbox. Due to the cost effective technical regulations in Rallycross, aids such as an electronically controlled gearshift system and traction control are prohibited.

There is an eight-tire limit for each competition – with an additional eight rain-tires available for a ’wet race’. The RX World series uses a controled tire (Cooper).

Power, traction and acceleration speed are the key elements of Rallycross!
